After solving my electrcal problem my jetting is off and I have been fouling plugs when riding trails and getting on and off the throttle and running WOT. If I ride 3/4 and below the plug takes alot longer to foul. My question is do you think it's the main. I just put a leaner needle OBERT and diafram 3.3 in and was hoping this would solve the problem, but didn't. I have a 152 main and was thinking of dropping it in, but I am looking for a second opinion.
